What is the optimal temperature to sleep at?

The one where you sleep the deepest and longest so you heal naturally and feel great. This is different for each person and often varies by night.

Sleep studies show the ideal sleep temperature for optimal rest & recovery is 60-68ºF. But since everyone is different, it might take about 2-3 weeks to find your own sweet spot. It's also important to note that your temperature will change as the seasons change.
